WINDING-INDICATOR FOR TIM EPlECES.

SPECIFICATION forming part of Letters Patent No. 663,263,, dated December 4, 1900.

Application filed December 23, 1899.

Serial No. 741,431; (No model.)

Too/ll whom it may concern/.-

Be it known that 1, AUGUST ELENIUS, a subject of the Czar of Russia, (but having made oath of my intention to becgme acitizen of the United States,).and a resident of Calumet, in the county of Houghton and State of Michigan, have invented certain new and useful Improvements in Devices for Indicating when Olocks Should be Rewound; and I. do declare the following to be a full, clear, and exact def scription of the invention, such aswill en- 'able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawr 5 ings, and to letters of reference marked there.- I on, which form a part of this specification.

Figure I of the drawings is a front elevation of a clock having the invention applied thereto. Fig. 2'is a detail view of my device.

This invention has relation to means for indicating when a clock is nearly run down and should be wound; and it consists in the novel construction and combination of devices, as hereinafter set forth. 2'5 In the accompanying drawings theletter A designates the axis of the mainspring, and B an attachment thereto, consisting of a small pinion, which is located near the inner'surface of the face-plate F of the clock;

0 represents a large sector-gear, which is provided with a central bearing d, which engages a journal 6, which may be secured to the face-plate of the clock. This gear-wheel is in the same plane with the pinion B and is 3 5 engaged thereby. The sector-gear O carries a winding-sign, usually an arc-plate H, which is designed to register with a sight-aperture K made in the face-plate. This arc-plate is for the most part colored in accordance with of the clock-face, generally white, but at the part marked J it is providedwith the words Wind me or Wind or some like sign to call attention to the need of winding. For a short distance in'rear of this wording or sign the arc-plate ,is colored black, as indicated at n, to indicate that the need of-winding continues.

While the clock is running,the part or shows through the sight-aperture until in ordinary 5o clocks the running has continued for twentyfour hours, whenfthe signal to wind appears as indicated at m;

at the opening. I Then the clock should be wound, this action reversing the movements of the pinion and sector-gear'and turning the,

arc-plate back, so that the part or again shows. If, however, the clock is neglected, the sectorgear continues to move and the black part of the arc-plate comes into view, showing that the clock still needs winding.

By properly-combined gearing the principle can be adapted to eight-day clocks as well as to others having'even alonger period of run ning before winding is necessary.

In some cases an entire cog-wheel may be used to carry the arc-plate; buta sector-gear is preferred, as indicated, provided the num-,. ber of teeth thereon is properly proportioned to the number of teeth of the small pinion on the axis of the mainspring, so that the arcplate will show continously at the sight-aperture in the face-plate.

Having described this invention, what I claim, and desire to secure by Letters Patent,

1. In clock mechanism, the combination with the dialplate having a sight opening, and a pinion on the axis of a shaft in driving engagement with the clock-train, of a pivoted sector-gear driven by said pinion, and having an arcuate band registering with said sightopening of the dial-plate, and divided into two arcuate portions, one preceding and of a contrasting color to the other, substantially as specified. I

2. In clock mechanism, the combination with the dial-plate having a sight-opening,

and a pinion on the axis of a shaft in driving engagement with theclock-train, of a pivoted sector-gear directly engaged and continuously driven by said pinion, and having an arcuate band registering with said'sightopening of the dial-plate, and divided into a' long arcuate white colored portion, and a short arcuate black-colored portion,the word Wind being marked between such white and black portions, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

AUGUST ELENIUS.
